JOHN E. LEONARD, OF PORTLAND, OREGON.

MOVING-PICTURE MACHINE.

Specification of Letters Patent. Application filed March as; 1912.

Serial No. 686,908.

'1 '0 all whom it may concern Be it known that'I, JOHN E. LEONARD, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Moving-Picture Machines, of which the following isa specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in moving picture machines.

The object of my invention is to provide means for feeding the film across the lens and'to dispense with the usual perforations necessary in the edge of the film, although films having these perforations can be readily used upon my machine.

Another object of my invention is to provide means whereby the film can be started from the reel and will be guided directly of its own accord to the feeding mechanism.

and then guided to the reel upon which it is wound.

A still further object of my invention is to. provide a more simple, cheap and effective means for feeding the film across the lens and intermittently stopping and start ing the same for exposing the picture.

In the accompanying drawing Figure lis a side elevation of my improved moving picture machine showing the internal drive gear removed. F1 22 is a side elevation showing the hinged si e swung outwardly exposing the film feeding mechanism. Fig. 3 is a vertical longitudinal sectional view of Fig. 2, showing the feeding mechanism on its upward movement to again engage the film.

Fig.- 1 is a vertical sectional View similar to Fig. 3, showing-the film gripped by the feeding mechanism on its downward movement. Fig. 5 is an enlarged sectional view of the winding spool showing the manner of 'attaching the film thereto.- Fig. 6 is an enlarged plan View of the film engaging member 18.

Referring now to'the drawings, 1 represents a rectangular casing having at'its forward edge an opening- 2, opposite the lens '3, and said opening is closed by a slide 3, all ofwhich is of the ordinary structure of amoving picture machine. .One side of the.

casing is hinged at'4.- whereby access tothe interior mechanism of the machine may be readily had. Therear edge of the casing is provided with a hinged door 5, for the entrance of light from the lamp when pro- Patented July 7, 1914."

new films or removing old ones from the machine.

The easel, at its forward end, as hereto fore stated, is provided Wit-h a lens 3 opposite theppening 2, although the lens could be applied on the outside of the machine. The lens as shown is permanently supported between the sides of the casing, and surrounding the lens is a rotary shutter 8 having at its outer end a gear 9 on the out-' side of the hinged cover 1, whereby the shutter is rotated around the lens. The specific construction and arrangement of this lens is fully described in a co-pending application filed March 3rd, 1911, Ser. No. 612,126 and needs no further detailed description.

Below the shutter is mounted a transverse A shaft 10 having an eccentric 10" arranged thereon and surrounding said eccentric is a' band v 11 carried by the arm 12 pivoted at 12 The {outer end of the shaft 10 extends through the hinged cover 4 of the casing and is provided with a gear 14 by means of which and secured to said arm is a pitman 13/ the shaft 10 is rotated, all of which will be hereinafter more fully described. j

The casing 1 is provided with a vertical divisional p1ate14, having an opening 15 therein opposite the lens. Carried. by the divisional plate 14' is a plate 16 to which is rigidly secured a spring arm 17, having at its lower end a soft enlarged film engaging portion 18, which is adapted to engage the film and press it against the divisional plate 14: and hold the film stationary while the shutter is open. The spring arm 17 normally holds this soft enlarged portion 18 against the film. The pitman 13 has its outer end pivotally connected at 19 to the member 18 carried by the spring arm 17, whereby the film is intermittently gripped and held stationary while the shutter is open.

The divisional plate 14 has guide-Ways 20, in which the vertically movable film carrying member 21 vertically slides. The upper end of said film guide 21 is provided with an outwardly extending arm 22, to which is pivotally connected at 28,fthe pitman 24, which extends downwardly and is connected to a wrist-pin 25, carried by the disk 26. The said disk 26 is rigidly seciired I carries on the outer side thereof a gear 28, by meansof which the said shaft is rotated.

. .opening 29, through which passes a film engaging member 30, carried by the pltman traveling upwardly.

to the shaft 27, which extends outwardly through the hinged side 4 of the casing and The rotation of .the shaft .27, as will be seen, will cause the fihn carrying guide 21, to reciprocate in the guide 22, as heretofore stated. ,v

The film guide-21 is provided with an clamps the film against the rear wall thereof,

downward movement of the film the desired distance "The 'pitman 24, as clearly shown is of a broad form and has an elongated opening 24 of sufiicient length to at all times expose that portion of the film opposite the opening 15 in the divisional plate 14, whereby the reciprocation the continued pitman draws the the exposure of the picture. The reel carrying frame or box 7 is of the usual form having a reel 31 at its upper end, and a reel 32 at its lower end. The film-carrying member 7 adjacent the reel 31 is provided with' an opening 33 and on the outside of the frame 7 a roll 34 is provided over which the film is adaptcd'to pass.

The casing 1 is provided with a roller 35, driven by a gear 36 on the outside of the cover 4. The film passes between the rollers 34 and 35 and is fed outwardly to the groove plate 37 which. leads downwardly within the flared upper end 21 of the film carrying guide 21. 2

' Below the lower end of the film carrying guide 21-the casing is provided with a grooved plate 28 which leads upwardly to an opening 39 in the film carrying frame? The film 40, as clearly shown in Fig. 3 of the drawings, travels outwardly through the opening 33 between the rollers 34 and 35 and follows the curva' 'ture of the plate 37 entering the upper flared end of the film guide 21 and passes downwardly through the same. As the film leaves the guide 21, it engages the curved plate 28 and isguided through the opening 39 into the reel carry ng frame 7 and is wound upon the spool 32.

It will be seen from the drawing that the spool- 31 is not driven, but that the feeding guide 21 unwinds the film therefrom. The

and the guide "shaft 41 of the spool 32 extends outwardly through air-opening in the hinged cover 4- and is provided with a friction disk 43 which engages the outer periphery of the internal gear 44.

The hinged cover 4, of the casingv is provided with a stud 46, upon which is mounted the internal gear 44. The gear 44 is provided with a handle by means of which it is readily rotated. In Fig. 1 of the drawings it will be readily seen that the gears 36, 9, 2S and 14 are so located that they engage the internal gear 44 and the rotation thereof causes each and all of said gears to rotate at the proper speed.

From the foregoihg description it will be seen that the film is at all times within the film guide 21 and the arm 12 and the pilinen 13'and 24 are so arranged in respect to each other that the film gripping member 18 is holding the film tightly against the divisional plate when the film carrying member is traveling upwardly. hen the film is thus gripped the shutter of the lens is opened to expose the film As the shutter closes, the pitman 24 has reached its upward stroke and the film engaging member 30 passes through the opening 29 and grips the film against the rear wall of the guide 21 and a continued downward movement of the pitman. draws the film downwardly at a distance equal to another picture. As the film starts on its downward movement the pitman 13 has forced the member 18 outwardly to release the film and allow it to be drawn or wound upon the roll 32. This operation takes place as long as the internal gear 44 is rotated. The movement of the shutter S and the movement of the pitmen 13 and 24 are so timed that when the shutter is opened exposing the film the gripping member 18" is holding the film against the partition 14 21 is traveling upwardly to again grip the film and feed it downwardly for another picture.

The film engaging and gripping member 18 is provided with a central cutaway porlion 18 leaving at each end the film engaging flanges l9 and 20 which engage the edge of the film beyond the picture and thus prevent any scratching 'or marring of the picture on the film.
